Do you have a linky for that?
www.bountifulgardens.org
This is their website. They have a lot of books and booklets. One section of their catalog is devoted to Survival and Self Sufficiency reading materials.
Their catalog has a handy chart for cover crops and their benefits along with the planting season for the crop.
I have lots of problems with looking at their publications and seeds. I want them all. LOL Always something interesting and new to read or plant.
